GUMMING MECIIANISM FOR BOX-MACHINES, 86C.

To all whom it may concern:

Be it known that I, CHARLES E. VVHrrE, of Quincy, in the county ofNorfolk and State of Massachusetts, a citizen of the United States, haveinvented a new and use ful Improvement in Gumming Mechanism forBox-Machines and the Like, of which the following is a specification.

My improvement rel ates more particularly to the class of guminersdescribed in an application. for Letters Patent of the United States,filed June 9, 1906 by Eugene H. Taylor, Serial No. 321,032, in whichthere is shown a gum box into which the gummer descends until it issubmerged in the gum and then rises into contact with the under surfaceof the blank to which the gum is to be applied.

In the preferred form of my gummer the gum is applied by a series ofindependent fingers which are held in clusters in a frame, each finger,however, being capable of yielding independently of all the others,preferably against the force of a spring which will return it to itsnormal position, and each finger preferably, also, having a slightcavity in its gumming tip so that each finger will carry not only thegum which would naturally adhere to it but also the gum .contained inthe cavity from the gum box, to the surface to which the gum is to beapplied. In a gummer of this character a somewhat longer stroke shouldbe given than in the case of the gummer described in the Taylorapplication for the reason that the gumniing fingers all yield and hencemay be used to impress the blank with gum.

My invention will be understood by reference to the drawings, in which--Figure l is a vertical section through the gum box showing the submergedgummer. Fig. 2 is a plan view of the gummer. Fig. 3 is a plan of theunder surface of the gummer. Fig. 4 is a section on line H of Fig. 2.Fig. 5 is a section on line 55 of Fig. 2, and Fig. 6 is a sect-ion online 66 of Fig. 2.

A is the gum box which is supported in a suitable manner as for exampleby brackets c upon the box-making machine the frame of which is shown atA A reciprocating rod A passing through an eye A carries at its lowerend the frame of the guinmeii'. This frame may be of a variety of shapesaccording to the shape of the surface of the blank to which gum is to beapplied, and in strengthened by aweb 0.

the same way the gum-carrying surfaces are arranged according to theshape of the said surface of the blank.

The frame as shown in the d 'awings comprises two supports B, B whichare attached by screws I), b to a yoke-piece C carrying an eye 0 whichfits onto the reciprocating rod A and is held in place thereon by a setscrew a The yoke-piece C is preferably The means for attaching theyoke-piece C to the rod A will not be further described in detail as itis fully described in the said Taylor application, but in the presentcase each arm of the yoke-piece has a slot c 0 through which the screwsZ), 6 pass and each screw has on its lower end a nut b so that bylooking each screw, the position of each support B, B may be adjustedtoward and from the axis of the reciprocating rod A after which thescrews are tightened again.

The guinming sections comprise rectangular boxes D, D of which the twoends are open. Each side of each support B, B is slotted as atand setscrews d are provided which pass through these slots-and into the sidewalls (Z of the boxes. The top (Z of each box overlaps the sides andforms a rest which rests upon the sides of its support, the top of thebox being held to its sides by screws (Z The fingers by which the blanksare gummed are shown at E. Each has a collar c which limits the upwardmovement of its finger through the top of the box, the under surface ofthe collar'serving also as a rest for its spring 6 the lower end of thespring resting upon the inner surface of the bottom (1* of the box, thisconstruction being such that any pressure upon the top of a finger willdepress it, but when the pressure is released the finger will resume itsoriginal position. These fingers pass through both the top and bottom ofthe box so that these parts serve as guides to the fingers insuringtheir movement in a right line and hence preventing any binding orbending of any finger. Each spring 6 encircles its finger. Each fingerhas a slight cup-shaped cavity a in its top sufficient to hold say adrop of gum.

hen it is borne in mind that the stroke of the reciprocating rod A issufficient alternately to submerge the gummer in the gum box, as shownin Fig. 1, and to cause ferent gumming sections may be used upon such anengagement of the gummersWith instead of conveying gum .to a surface itthe under surface of the blank to be gummed that they will allbedepressed more or less,

it is believed that the utility as well as the operation of thismechanism willbe understood, and it ,shouldbe further borne in mind thatby loosening the screws 6, b the supports carrying the gumming sectionscan be moved farther from ornearer to the axis of the reciprocating rodA and by loosening thescrews d the gumming sections may be moved nearerto or farther from each other as the case may be so that asingle gummermay be adjusted to the size of blank to be gummed. It is moreoverapparent that difthe same frame according to the surface to be gummed. IIt is apparent that while thisdevice as shown is a gumming device, asitmakes impressions of gum upon the blank, it becomes 1n fact a prmtmg ormarking device and may be used equally well with printers ink or othersuch material with which it is desired to impress a sheet or blank.

lVhat I claim as my invntioiiisz- 1. A gummer comprising a yoke, twoframes adjustably mounted, one on each arm of said yoke, a box locatedin each frame carrying adjustable fingers, said box being adjustable insaid frame, as described.

2. A gummer comprising a yoke, two frames adjustably mounted one on eacharm of said yoke, 21. box located in each frame carrying self-adjustingfingers, said box being adjustable in said frame, in combination with areciprocating rod, sai(l gummer being adjustably mounted thereon, as setforth.
